PUMP ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed April 27, 1904- Serial No. 205,183.

To aZl whom it may concern.-

Be it known that I, WILLIAM H. ZORN, a citizen of the United States, residing at Gary, in the county of Banner and State of Nebraska, have invented a new and useful Pump Attachment, of which the following is a s ecification.

his invention relates to pumps, and more particularly to pumps that are operated by windmills.

The principal object of the invention is to provide a device of simple construction which may be readily applied to existing pump structures and which will operate to prevent or lessen the jarring and irregular motion of the pump-plunger.

A further object of the invention is to pro Vide a device of this class which may be readily adjusted in accordance with the degree of force exercised in the operation of the pump.

WVith these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con struction and arrangement of parts hereinafter fully described, illustrated in the accomp anying drawings, and particularly pointed out in the appended claim.

In the drawings, Figure 1 is a side elevation of a pump attachment constructed in accordance with the invention, arts being l early illustrate the construction. Fig. 2 is a front elevation of the same. Fig. 3 is a detail perspective View of one of the spring-attaching blocks detached.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The pump 10 may be of any ordinary construction and in the present instance is shown as provided at its top with a laterally-extending flange 28. The plunger-rod 11 is of any ordinary construction and extends upward above the top of the pump for connection to the windmill or other operating mechanism. (Not shown.)

In carrying out the invention two generally rectangular blocks 12 and 13 are employed, the lower block 13 being rigidly secured by bolts to the flange 28, while the upper block 12 is held from upward movement. on the plunger-rod 11 by means of a key or pin 12, and the point of connection of the upper block to the rod may be altered in or der to increase or decrease the effectiveness of the springs which connect the two blocks.

The opposite ends of the block 12 are provided with recesses forming. spaced ears 14 and 15, and the lower block 13 is provided with similar recesses forming spaced ears 16 and 17, the upper and lower recesses being arranged in the same vertical planes, and each pair of ears is provided with openings for the passage of pins 18 19.

The blocks are coupled together by bowed springs 20 21, formed of strips of steel or similar metal, having straight parallel edges and of a width corresponding approximately to the width of the recesses. The ends of said spring are turned to form eyes for the passage of the pins 18 19, said springs being thus pivotally connected to the blocks, while the side edges of the springs bear against the vertical walls of the recesses and serve as a means of preventing any rotative movement of the upper block 12 and the plunger-rod with respect to the lower block 13.

The springs exert their force in raising the block 12, and thus assist the operating means in raising the column of water, While on the downward movement, where there is less resistance, the springs will tend to some extent to check or retard the operation, so that the jerking irregular motion of the pump, due to irregularity of load, will be prevented.

The opposite side portions of the lower face of block 12 are provided with recesses 24, disposed at points diametrically o posite each other, and the u )per face of the blbck 13 is provided with similar recesses 25, these recesses being arranged to receive auxiliary springs 26 27, which may be added when it becomes necessary to increase the force exerted by the springs.

It will be observed that the recesses formed between the spaced ears are of considerable depth and extend for the full vertical height of the blocks, so that the edges of the sprin s 20 and 21 will engage against the inner si e walls of said ears in all positions, and thus hold the upper block from turning, while at the same time the springs are free to yield from the points at which they are attached, and there is no change in the point of attachment nor any chan e in the fulcrum of the movement of the block 12 may be.

I claim In a pump attachment, upper and lower blocks of generally rectangular form, the op posite ends of each block being provided with recesses extending for the full vertical height springs no matter w at the extent of vertical of the block and forming spaced ears, pins block on the plunger-rod of the pump,the opheld by the ears and extending across said posed faces of both blocksbeing provided recesses, bowed springs having straight par- 1 with spring-receiving recesses, and auxiliary 15 allel edge portions, the edges of the springs detachable springs having their ends entered engaging against the inner vertical walls, of in saidreceiving-recesses.

said ears and serving to prevent independent In testimony that I claim the foregoing as rotative movement of the blocks in all posimy own I have hereto afiixed my signature tions, the opposite ends of each spring being in the presence of two witnesses.
